Income Tax Calculator — Old vs New Regime (FY 2026-27 & 2025-26)
Enter your salary and deductions to see your tax under both regimes for FY 2026-27 (AY 2027-28) or FY 2025-26 — with §87A rebate, surcharge and 4% cess — and which one saves you more.
Old-regime deductions (80C/80D/HRA/24b) apply to the old regime only. New-regime slabs + §87A follow the selected FY. FY 2026-27 figures are provisional (carried forward from FY 2025-26) pending the Finance Act 2026. Estimate for salaried individuals; confirm with your CA.
Old vs new regime — how to choose
The new regime is the default from FY 2023-24. It offers lower slab rates and a ₹75,000 standard deduction, but disallows most deductions (80C, 80D, HRA, home-loan interest). The old regime keeps those deductions but taxes at higher rates with a ₹50,000 standard deduction.
The rule of thumb: the more you invest and claim (PF, insurance, rent, home loan), the more the old regime tends to win. If you claim little, the new regime usually does. There's no single answer — it's arithmetic, which is why this tool runs both and picks the cheaper one for your exact numbers.
New-regime slabs, FY 2026-27 & 2025-26
0–4L: nil · 4–8L: 5% · 8–12L: 10% · 12–16L: 15% · 16–20L: 20% · 20–24L: 25% · above 24L: 30%. Income up to ₹12,00,000 taxable pays no tax after the §87A rebate. FY 2026-27 figures are provisionally carried forward pending the Finance Act 2026.
Frequently asked
It depends on your deductions. The new regime (default) has lower slab rates and a ₹75,000 standard deduction but allows almost no deductions. The old regime has higher rates but lets you claim 80C, 80D, HRA, home-loan interest and more. If your total deductions are large, the old regime often wins; if not, the new regime usually does. This calculator computes both and tells you the cheaper one.
Under the new regime for FY 2025-26, a resident individual with taxable income up to ₹12,00,000 pays no tax due to a rebate of up to ₹60,000 (with marginal relief just above ₹12L). Under the old regime, the rebate is up to ₹12,500 for taxable income up to ₹5,00,000.
